Production method of radiation image conversion panel

Abstract

A method for producing a radiation image conversion panel containing the steps of: forming a stimulable phosphor layer on a substrate by a vapor deposition method to prepare a phosphor panel; hydrating the phosphor panel under a relative humidity of 30 to 60%; and sealing the phosphor panel with a moisture-proof protective film to prepare the radiation image conversion panel.

1. A method for producing a radiation image conversation panel comprising the steps of:
 forming a stimulable phosphor layer on a substrate by a vapor deposition method to prepare a phosphor panel; 
 hydrating the phosphor panel under a relative humidity of 30 to 60%; and 
 sealing the phosphor panel with a moisture-proof protective film to prepare the radiation image conversion panel. 
 
   
   
     2. The method of  claim 1 , further comprising the step of:
 dehydrating the phosphor panel by heating the phosphor panel at a temperature ranging from 60 to 160° C. after hydrating the phosphor panel. 
 
   
   
     3. The method of  claim 1 , further comprising the step of:
 heating the phosphor panel in an organic solvent gas before hydrating the phosphor panel. 
 
   
   
     4. The method of  claim 3 , wherein the organic solvent is a nonflammable fluorine-containing solvent. 
   
   
     5. A method for producing a radiation image conversation panel comprising the steps of in the order named:
 (i) forming a stimulable phosphor layer on a substrate by a vapor deposition method to prepare a phosphor panel; 
 (ii) heating the phosphor panel in air or in an inert gas; 
 (iii) heating the phosphor panel in an organic solvent gas; 
 (iv) hydrating the phosphor panel under a relative humidity of 30 to 60%; 
 (v) dehydrating the phosphor panel by heating the phosphor panel at 60 to 160° C.; and 
 (vi) sealing the phosphor panel with a moisture-proof protective film to prepare the radiation image conversion panel. 
 
   
   
     6. The method of  claim 5 , wherein the organic solvent is a nonflammable fluorine-containing solvent.
